NCT03454867

Brief Summary

Ischemic stroke is accompanied by a three to four hundred percent increase in the brain's extracellular fluid (ECF) and cerebrospinal fluid (CSF) concentration of glutamate, which diffuses and damages surrounding neurons. In this study we tested our hypothesis that blood glutamate levels can be reduced by hemofiltration, resulting in increased extracellular clearance of glutamate and attenuated neurodegeneration, and that decreased blood glutamate levels can provide significant neuroprotection against stroke-associated neurodegeneration, dysfunction and death. Our primary outcome of interest was to assess safety of hemofiltration in acute ischemic stroke patients.

Model Details: Hemofiltration protocol. Hemofiltration was started after all enrollment criteria (informed consent, inclusion/exclusion criteria checklists, registration and assignment to treatment arm) had been met . Vascular access was secured by inserting an 11F double lumen catheter (GamCath, Gambro, Germany) into the jugular, femoral or subclavian vein. CVVH (continuous veno-venous hemofiltration) was carried out using a hemofiltration machine (Fresenius Multifiltrate, Germany). In all patients a 1.9 m2 highly permeable cellulose triacetate hemofilter was used (NIPRO UF205, Nissho corporation, Japan). All patients were treated by CVVH with the predilution mode; the blood flow was set at 180 ml/min.
